write an expression for the overall reaction rate, r, in terms of the rate step 3, r3 2. using the answer from 1, obtain an expression for the reaction rate, r, in terms of rate constants and concentrations of reactants and products, only use PSSH.

1. A carbohydrate (S) decomposes in the presence of an enzyme (E). The reaction follows Michaelis-Menten kinetics. The Michaelis-Menten kinetic parameters for this reaction are KM = 200 mol m3 and Vmax = 100 mol m³ min1. The initial concentration of substrate [So] = Cso = 300 mol m-³. -3 (a) If the reaction is run in a batch reactor, calculate how long the reaction has to be carried out to achieve a final substrate concentration that is 50% of the initial concentration. (Ans: t = 2.89 min) (b) If the same reaction is run in a CSTR, calculate the steady state substrate concentration at the outlet. The reactor volume is 300 cm³. The inlet substrate concentration 300 mol m³ and the volumetric flow rate is 100 cm³ min ¹. Also calculate the conversion achieved. (Ans: [S]e = Cse=164.6 mol m³ and Xse = 0.451) (c) Calculate the volume of a plug flow reactor required to achieve the same outlet substrate concentration when operated at the same conditions as the CSTR in (b). (Ans: V = 255.5 cm³)
